Dean was looking through the books in the library of the bunker. He was trying to find any way to lock up a pagan god for even a little while. Sam was out jogging and Cas was in the shower. Dean was stumped when he heard Sam come in.
"I don't understand why you run for fun," Dean complained for the millionth time, "We have to run every day of our goddamn lives to survive."
"It clears my head." Sam replied, looking annoyed with dean's remark. Sam looked around for a moment before continuing. "where's Cas?"
"Shower" Dean grunted still focused on the texts in front of him.
Sam, who knew what dean was doing, put a hand on Dean's shoulder. Dean looked up at Sam and Sam said, "Dude, they're gods. you can't trap them, Only trick and kill."
Dean sighed and closed the books. he stood up and made his way to the kitchen.
"I need a sandwich." Dean mumbled. He had just started assembling his sandwich when he felt a presence behind him. He turned around to see Cas's blue orbs. Cas was in one of the Men of Letter's bathrobes with the majority of his pale legs showing. Cas's dark hair was still wet and drops of water ran down his neck. Dean realized he wasn't breathing so he took a deep breath before speaking.
"Hey Cas." He gestured to his Sandwich, "Want one?" Cas nodded and took a seat at the table. Dean turned around and got back to work. Dean didn't know when these feeling has started. Somewhere around when the brought human Cas into the bunker. Seeing Cas so vulnerable and dependent on Dean, struck something in Dean. Dean tried desperately to push these feelings away but it was getting harder to ignore the truth. Dean place Cas' Sandwich in front of him, and sat down with his own on the other side of the table.
"Thanks Dean." Cas said with a smirk. Dean's pulse quickened and he distracted himself with his sandwich.
Cas knew perfectly well what he was doing to dean. After all his time looking down on earth, his favorite thing was human reactions. How a simple touch can increase a heartbeat. Cas didn't want to make the first move though, he knew Dean was in denial of his feelings and might embarrass Cas, if Cas said anything now.
Meanwhile, Sam was re cataloging the archive. After months he was finally on the "M"s. It wasn't long before he started thinking. He thought about Dean and how strangely he's been acting. It was as if Dean was constantly trying to distract himself. First with girls, then the job, and now he's resorted to research. Then there was Cas. Sam sometimes thought Cas was taking being human a little too well.
Dean and Cas walked out of the kitchen, tension radiating off of them. Dean was going to take a cat-nap when they heard knocking on the Bunker door.
"you guys expecting anyone?" Cas asked. Dean noticed, and adored, the way Castiel's eyebrows furrowed together.
Dean and Sam looked to each other and Sam shrugged. More knocking was heard from above. Dean made his way up the staircase leading to the entrance, with Castiel and Sam following close behind. As Dean went to open the door his right hand instinctively reached into his pocket grasping on to his gun. The three men were shocked to see who was on the other side of the door.
